    基于地形地貌因子的大关县堆积层滑坡孕育规律研究

    RESEARCH ON THE FORMATION LAW OF THE ACCUMULATION LAYER LANDSLIDE IN DAGUAN COUNTY BASED ON THE TOPOGRAPHY AND GEOMORPHLOLGY FACTORS

    • 摘要: 为了揭示复杂山区堆积层滑坡的孕育规律,本文基于大关地区98处堆积层滑坡的基础资料,利用综合影响指数分析法,展开地形地貌因子对滑坡发育程度影响指数的分析研究,划分不同因素对滑坡发育的影响指数等级。不同地形地貌条件对堆积层滑坡发育、发生的影响程度差异很大,高差中等(60~90m)、坡向北东、西向(NE,W)的凸型(T)、缓(21~35)斜坡最利于滑坡的发育。在分析结果的基础上,初步建立滇东北山区基于地形地貌因素的堆积型滑坡发育程度(条件)评价标准,为地质灾害调查提供一种快速判别不稳定斜坡发育程度的方法。

       

      Abstract: In order to reveal the formation law of accumulation layer landslide in the complex mountainous area, we carry out the analysis of influence index of topography and geomorphology factor on landslide development degree by comprehensive influence index analysis based on basic data of accumulation layer landslide at 98 sites of Daguan area, and divide the influence index grade of different factors on landslide development. The influence of different topography and geomorphology conditions on the development and occurrence of accumulation layer landslide is very different. The slow slope(21~35) of medium height(60~90m),North East, West convex type(T) is the most conducive to the development of landslide. Based on the analysis of the results, we establish the initial evaluation criteria of the occurrence level of accumulation layer landslide on the basis of topography and geomorphology factors in the mountain region of the northeast of Yunnan province, thereby provide a rapid identification method of the occurrence level of unstable slope for the geologic disaster investigation.
